At the beginning of September, I started preparing to upgrade the cooling system on the Mustang to include an electronic fan. The fan I selected is a 16" Flex-A-Lite Syclone fan (FLX-398 which has S shaped blades. To operate the fan, I purchased an adjustable Flex-A-Lite temperature controller (31147). The total cost for the items was around $142 from Summit Racing.
One the fan arrived, I removed the old fan and spacer from the Mustang. The fan blade was a six blade fan but it was not an original Ford fan. I placed it on eBay with another spare spacer I had which was too long for my Mustang. The set sold for $66 dropping the cost of this project to $82.
I installed the new electric fan today inside the stock fan shroud. It fit perfectly inside the shroud and is much more hidden from view. The casing for the controller was tan so I painted it with a little black paint to hide it better. I mounted it on the lower passenger side fan shoud bolt. The temperature probe is at the top of the radiator by the inlet hose.
I need to wire up a relay and fuse for the fan controller. I'm waiting on this part as I'm tempted to move the battery to the trunk. I'm not sure if I would leave the battery tray or not and I was going to hide the relay under the battery. I'll wait to finish this part of the project up until I decide on what I want to do with the battery.
The following picture shows the engine compartment with the standard fan:
This picture is from a little different angle but shows how the fan is concealed by the shroud.
This new fan generates 2,500 CFM of air when running. It should reduce the load on the engine when running at higher RPM. I'm not expecting an incredible improvement but it should help some. The only issue now is the 17amp draw on the alternator.
